As long as you use the heavier per caliber BT's you won't have a problem. The problem with the old bt's was fixed long ago. I have shot about 40 mule deer with them in calibers from the 250 Savage to the 300 Win Mag. Not a single bullet failure. I had a few come apart in the 7 Mag 10 years ago or so. But they have been redesigned so that the lighter ones are made for varmiting and the heavier ones for big game.
